Morphology

dizygous = zygous (transparent) = di + zyg + ous

Formed by the productive prefix 'di-' (two) added to 'zygous' (pertaining to a zygote), so the meaning 'from two zygotes' is compositionally clear.

Etymology

Dizygous comes from the parts di- 'two' and zygote 'fertilized egg'. So dizygous describes twins that come from two separate fertilized eggs, which is why it means 'fraternal'.
